The paper introduces database and related techniques for a reconfigurable, intelligent 3D engineering shape search system, which retrieves similar 3D models based on their shape content. Feature vectors, which are numeric “fingerprints” of 3D models, and skeletal graphs, which are the “minimal representations of the major shape” of a 3D model, represent the shape content. The Euclidean distance...

Using the concepts of h-core and h-tail, shape descriptors and shape centroids, k-index and k′-index, dynamic measures are probed, with practical data in the fields of Physics and sociology. It is revealed that there are obvious differences between natural sciences (Physics, particles & fields) and social sciences (sociology) when c-descriptor, h-core centroid and kindex are applied as dynamic ...

Method for tealeaves quality estimation through measurements of Degree of Polarization: DP, Leaf Area Index: LAI, Photosynthesis Available Radiance: PAR and Normalized Difference Vegetation Index: NDVI for characterization of tealeaves is proposed. The method allows estimations of PAR, NDVI, Grow Index: GI by using measured Degree of Polarization: DP of tealeaves. Through experiments at the tea...

detection of lymph nodes (lns) involvement by various pathological processes has great therapeutic and prognostic implications. the purpose of this study was to evaluate the usefulness and accuracy of triplex sonography (gray scale, color mapping and spectral doppler) in differentiating benign from malignant cervical lns. we used triplex sonography to evaluate 120 lns in 50 patients. the gray s...

In the open ocean, many animals are highly transparent, some achieving near invisibility. However, little is known about how this transparency is attained. The effects of cellular ultrastructure on tissue transparency were mathematically modeled. Given a specific constant volume or surface area of a higher refractive index material (e.g. protein, lipid, etc.), within a lower refractive index cy...

The present study was conducted to determine egg production traits and egg quality characteristics in black and brown lines of Japanese quail. A total of 500 quails comprising 400 females and 100 males obtained from two breeding centers were raised according to the standard procedure for Japanese quail. They were grouped in according to their plumage colours. Age at first egg-laying has been re...

Textural patterns can often be used to recognize familiar objects in an image or retrieve images with similar texture from a database. Texture patterns can provide significant and abundance of texture and shape information. One of the recent significant and important texture features called Texton represents the various patterns of image which is useful in texture analysis. The present paper is...
